radiko Inc. (Representative Director and President: Takuo Ikeda, Location: Minato-ku, Tokyo), which provides the free service "radiko" allowing users to listen to radio and podcasts on smartphones and computers, has begun distributing the fourth installment of its original podcast program "Hikari Ota and 15 Speakers," commemorating the 15th anniversary of its service launch. This program is a special project where Hikari Ota of Bakusho Mondai, who is also a radiko 15th-anniversary PR ambassador, invites popular personalities representing various radio stations as guests to engage in discussions centered on the theme of "radio." In the first episode, Takashi Okamura of Ninety-nine from Nippon Broadcasting System appeared, in the second episode, Chris Peppler from J-WAVE, and in the third episode, Jane Su from TBS Radio, all sharing their thoughts on radio.
Following them, the guest for the fourth episode is voice actress Kana Hanazawa, who has served as a personality for 18 years on Bunka Hoso's "Meiji presents Kana Hanazawa no Hitori de Dekiru kana?". A self-professed long-time fan of Bakusho Mondai, she engaged in an intense one-hour discussion with Ota.
In the program, Hikari Ota, who calls himself the "oldest anime otaku," passionately articulated the appeal of anime works from the Showa to Reiwa eras. His talk with Kana Hanazawa, who has been active in numerous popular works, developed into deep topics such as character expression and the profoundness of works down to fine details. Furthermore, the content is rich with diverse themes, including episodes from Kana Hanazawa's radio program and stories related to her private life.
